Search near or far, seek high and low;
Of all the places you could go
The one your noise that's sure to foil
Is wondrous Marvel Mystery Oil.

Why sailors up and down the coast
When sticky valves their buns do roast
They leap ashore and on the boil
Seek out the Marvel Mystery Oil!
[Half a pint per tankful for the L-head Atomic Four marine engine
which is also prone to sticking piston rings]

I also find it's good for me,
Bosch blower fans, their shafts to free.
My e-motions no longer roil
When I use Marvel Mystery Oil.

A pleasant penetrant it is,
You squirt it on both hit and miss.
It leaves behind some good lube oil;
All Hail the Marvel Mystery Oil!

Which I rather suspect is what you're actually talking about.

Yours,
David
